A team at the University of the District of Columbia in the nation's capital has created a garden on the top of one school building. The garden holds many kinds of plants to help absorb rainwater and grow food at the same time. Architect David Bell has designed five "green roofs" for the university. He says he is excited about the project because "it meant doing something more than just dealing with storm water management. It took advantage of a resource above the city and these flat roofs that aren't doing anything really became something that was about urban agriculture. " Rainwater is collected in large containers and sent through a system that waters the rooftop garden. The roof is filled with green life that appeals to insects.

In cities, “you don't have that many spaces to choose from and so rooftops are just (unused) space," says Caitlin Arlotta. She is a student in the school's Urban Agriculture program. The project is part of a research program to see which plants do well on rooftops. The researchers are looking at plants including strawberries, tomatoes and sweet potatoes. The university also has other green spaces. "We also have our own farm experiments," Arlotta said. “ Within each of those growing systems, we want to be able to tell people which sorts of these crops grow the best. "

Sandy Farber Bandier helps run UDC's Master Gardener program. It seeks to improve cities and make them beautiful by training people to become Master Gardeners. She says she's been surprised by the garden's output. ”My biggest surprise was that we produced 4, 250 pounds of produce the first year and was able to spread that to people in need. " She also likes being able to show people who live in D. C. and others beyond the nation's capital what and how food can be grown on a rooftop. “This is the future for food. You grow it here, you prepare it in a commercial kitchen, you distribute through farmers markets,food trucks, and then you recycle. "

The team trained the youngsters to fly in a large wind tunnel wearing backpacks and face masks full of sensors that recorded their heart rate. blood oxygen levels, temperature, and metabolic rate—how many calories they burned per hour. The researchers simulated(模拟)10w-, medium-, and high-altitude conditions by altering the concentration of oxygen supplied to face masks worn by each goose as it flew in the tunnel.

Birds already have a better heart and lungs than mammals for sustained physical activity. And researchers knew that bar-headed geese have even larger, thinner lungs that let them breathe more deeply and an even bigger heart to pump more oxygen to muscles than other birds.

The wind tunnel experiments showed that when the concentration of oxygen was at its lowest-like the 7% found on top of Mount Everest versus 21% at sea level—the geese's heart rate and frequency of wing beats remained the same even as their metabolic rate dropped. Somehow, the birds managed to cool down their blood-the measured blood temperature droppedso it could take in more oxygen, the researchers report today in eLife. This cooling likely helps compensate for the very thin air, the team says.

Although well trained, the birds were only willing to stay in the air a few minutes-or Iesswhen wearing their backpacks and flying at 6ihigh" altitudes. So it's not clear whether these adaptations alone are what make it possible to fly the 8 hours it takes to climb over Mount Everest. But those few minutes showed these geese really could fly over the top of Mount Everest.

【1】Why did the researchers raise 19 bar-headed geese and train them?

A.To test the flying height and speed of them.

B.To confirm they could fly over Mount Everest.

C.To observe them flying through the wind tunnel.

D.To see how many calories they burned per hour.

【2】What can we learn from the wind tunnel experinent?

A.It was carried out at very high altitude.

B.The geese managed to breathe less when their blood decreased.

C.The geese could live through the lowest concentration of oxygen.

D.It shows the geese could fly at high altitude for long.

【3】What still puzzles scientists about the geese?

A.Whether they have super hearts and lungs.

B.Whether they have muscles pumped more oxygen to.

C.Whether they are willing to wear backpacks and face masks.

D.Whether they can manage to fly 8 hours to climb over Mount Everest.

【4】Where does the text most probably come from?

A.A science fiction.

B.A climbing guide.

C.A travel brochure.

D.A science report.

Dear students and parents.

As our state continues to fight against the spread of COVID-19, the State Board of Education has voted to authorize the closure of all public schools in Oklahoma for the remainder of the 2019-20 school year.

Jenks Public Schools (JPS) will be transitioning to distance learning beginning April 6 through the end of the school year. All JPS school buildings and facilities will remain closed until further notice. All activities, athletic events, club meetings, school sponsored trips are canceled for the 2019-20 school year.

JPS administrators are working on plans for a district-wide distance learning program. Please be patient over the next week as these plans are finalized. As soon as more information is available, you will be notified.

The time being missed due to the coronavirus-related closure will not have to be made up. Summer will not be shortened and as of now, the start of the 2020-21 school year will not be delayed.

We recognize the disappointment and difficulty this closure is causing our students and families. Our thoughts go out to our senior class knowing they will not have the opportunity to walk across a graduation stage in front of their family, friends, and peers. Please be assured, we will find a way to honor our seniors and recognize their achievements.

None of this is easy but despite our distance, we are still one Trojan family. We will continue to love and support each other. We will always make decisions based on what is best for our students. Thank you for your trust. You will hear from us very soon.

Sincerely,

JPS Administration

When it comes to the season I like best, spring will always strike to me in no time. There are many reasons that I like spring best. One of the most romantic thing is to walk in a lightly rain in spring. What’s more, after a long cold winter, everything begin to come to life. But whenever there is a chance for me to go to the countryside, I will never hesitate to pack my bags and leave to the land. Finally, I adore spring because it is either too hot nor too cold. In word, I like everything in spring, especially the sight of green trees bathing in the sunshine.
